Hello everyone, is there a way for starting a task, if and only if, a sub-workflow has failed ? Let's say I have a workflow of 3 sequential tasks, and I'd like a 4th task to be ran if, and only if, one of the 3 tasks fails.

but, this is infact supported in the backend through

failure nodes

but not implemented in flytekit python today

but someone could implement it

so the support is for something like try: task1 task2 …. catch: do_something

here is the issue - https://github.com/flyteorg/flyte/issues/1506

please upvote
